by DukeWhite, Verified Owner from MI, United States Written on June 18, 2024
You’ve got a suppressed 300 Blackout AR— why not go all in with these amazing subsonic designed bullets from Hornady. 190 grains of goodness. Designed to expand at these low speeds. Great product at a great price.

Best Used for:
  • Home defense
